I loved Obra Dinn and yet when you said that I drew a complete blank. What I remember of Obra Dinn is figuring out the metapuzzle. And maybe the Kraken.
I think the problem with "gaming moments" is you need a kind of universally communal experience of a game. The reason the Mexico ride in Red Dead became the prototype for THAT is it was maybe the last time we were all playing the same thing at the same time and reading the same things so we could all talk about the same bit at the same time.
